Mycetoma is a neglected tropical disease that predominantly affects individuals in low socioeconomic strata, primarily in tropical and subtropical regions. This case report describes a 20-year-old male student from Bahdo City, Somalia, who presented with a persistent cervical mass following a history of trauma. The patient exhibited vital signs within normal limits, and imaging studies, including ultrasound and computed tomography, revealed well-defined cystic masses.

Rift Valley fever (RVF) is a devastating zoonotic mosquito-borne viral hemorrhagic fever disease that threats human and animal health and biodiversity in Africa, including in Rwanda. RVF is increasingly outbreaking in Africa, leading to devastating impacts on health, socioeconomic stability and growth, and food insecurity in the region, particularly among livestock-dependent communi-ties. This systematic review synthesizes existing evidence on RVF's epidemiology, transmission dynamics, and the prevention and control measures implemented in Rwanda.

Sub-Saharan Africa continues to bear a disproportionate burden of the global HIV epidemic. Integrating HIV services into primary healthcare is a crucial strategy to accelerate progress towards ending the epidemic. However, several challenges hinder effective integration, including underfunding, human resource shortages, infrastructure limitations, weak health systems, and sociocultural factors.

Background: Rwanda has made remarkable progress in scaling up HIV testing, treatment, and healthcare services. Recent data show that 95% of people living with HIV (PLWH) were aware of their status, 97.5% of them are on antiretroviral therapy (ART), and 98% of those who are on treatment have achieved viral suppression.

In this review, we investigated the genetic diversity and evolutionary dynamics of the species that includes both Marburg virus (MARV) and Ravn virus (RAVV). Using sequence data from natural reservoir hosts and human cases reported during outbreaks, we conducted comprehensive analyses to explore the genetic variability, constructing haplotype networks at both the genome and gene levels to elucidate the viral dynamics and evolutionary pathways. Our results revealed distinct evolutionary trajectories for MARV and RAVV, with MARV exhibiting higher adaptability across different ecological regions.
